Invitae RCV000689472 SCV000817125 uncertain significance Amyotrophic lateral sclerosis type 4; Spinocerebellar ataxia autosomal recessive 1 2018-01-23 criteria provided, single submitter clinical testing This sequence change replaces phenylalanine with leucine at codon 2554 of the SETX protein (p.Phe2554Leu). The phenylalanine residue is weakly conserved and there is a small physicochemical difference between phenylalanine and leucine. This variant is present in population databases (rs368269464, ExAC 0.01%). This variant has not been reported in the literature in individuals with SETX-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The leucine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
